New Haven were in some cases almost defoliated, and the larvae were 

 observed feeding upon maple, chestnut and hickory. A hedge of 

 California privet was badly eaten, and oak trees at Stonington were 

 partially defoliated. At Old Saybrook the elms were considerably in- 

 jured last year, and the local village improvement society banded a 

 large proportion of the trees, which are old and large ones, but the 

 sticky bands were not placed upon the trees until after many of the 

 eggs had been laid, as it was supposed that the spring species, Palea- 

 crita vernata Peck, was responsible for the injury. Though both 

 species were present, the fall canker worm was far more abundant than 

 the spring species, and doubtless caused a like proportion of damage. 



A resident of Stonington, noticing the brown appearance of an ap- 

 ple orchard, inquired if it was the work of the gypsy moth, which is 

 in that vicinity, as he had seen the men working to combat it. An- 

 other remarked that we might better stop the gypsy moth work and 

 direct our efforts toward controlling the canker worm, as the latter 

 seemed to be doing more damage. In this region last year a similar 

 remark was made regarding the rose chafer. As a matter of fact, 

 the gypsy moth, which is known to be present in Connecticut only at 

 Stonington, where it infests not more than one square mile of territory, 

 has not been sufficiently abundant there to defoliate trees so as to 

 ])e noticed by the people. Many know of its presence simply by hear- 

 ing of it and by seeing the force of men at work. If its presence had 

 not been discovered, however, or if no attempt had been made to 

 control it, doubtless by this time it would have become so abundant as 

 to attract attention. At present al)out ten men are at work, 14,000 

 trees have been banded and something over 1,000 caterpillars have l)een 

 destroyed this season, in spite of the extremely careful search for egg- 

 masses last winter by both state and government scouts, some of the 

 ground being covered several times. Every effort is being made to 

 exterminate this colony, and though much scouting has been done in 

 other parts of the state, especially along the principal highways, no 

 gypsy moths have been found elsewhere. 



The peach sawfly, PampJiilius persicum MacGillivray, which was 

 so abundant in the orchards of Barnes Brothers, Yalesville, last year, 

 was greatly reduced in numbers by spraying with lead arsenate. The 

 owners sprayed between 4,000 and 5,000 peach trees during the last of 

 June and the first week in July, using from two to three pounds of the 

 poison to fifty gallons of water. An examination of the sprayed trees 

 June 25 showed practically no damage by the insect this year, only 

 an occasional leaf being eaten. In an unspraj^ed portion of the or- 

 chard some distance removed, the larvjv were nuich more abundant,
